Abstract

Layered structure transition metal chalcogenide compound’s such as Molybdenum sulfide (MoS₂) deposition in micro/meso porous architecture of MnO₂ could provide hybrid inter esting features. Multivalent MnO₂ is an attractive low cost and toxic free catalytic materi al for oxidation reaction and electrochemical applications. Non-ionic surfactant implica tion in mesoporous metal ion modified MnO₂ by deposition of metal chalcogenide is an ef fective composite for dye degradation applications. The low-cost pre-cursor makes it at tractive for large-scale production at industrial scale. Hence, in the present study deals with exploit the mechanism of metal chalcogenide and graphene oxide insertion in porous manganese oxide matrix. The as prepared l surface properties of the Nickel and cobalt doped manganese oxide/MoS₂ composite catalyst have shown effective congo red dye degradation activity. The complete color disappearance appeared after interaction with the composite catalyst.
